I am 32, I had my tubes tied 10years ago, got pregnant 5 years ago and have had normal periods all my life. This month I have had 2 periods, one normal flow, normal time. But 10 days after my normal expected period I began bleeding, first very brown and clotty, now very heavy, very red, and my cramps are completely different. What is going on with my body? Should I be worried or will this go away
